COLLECTION INFO: Ken Block's swagger and balls-out driving style helped shape the all new Helm. Ken asked for a vintage sunglasses design with aggressive lines. With his help, we delivered. The Ken Block Helm features his new signature livery and interchangeable temples for a fully-customizable look. Available 4/19/2012 at www.spyoptic.com.
